3f8aa662e9 add support for ref counts to memory allocator.
mark and sweep, stop the world garbage collector
(intermediate step in the way to ref counting).
can run pretty with an explicit gc after each file.

cc352e5c1c The DejaGNU testsuite harness used by the gccgo testsuite is
broken if you give it something which matches everything--the
.* swallows all the error messages.  Recognize some reasonable
error text directly.

cfb9425460 emit dynamically linked 6.out on darwin instead of static,
unless given -d flag.

the resulting binary doesn't *use* any dynamic libraries,
it just has a reference to the dynamic linker and an
empty list of needed symbols and libraries.

this is enough to make 6.out binaries that can be run
under dtrace / dtruss.

cb67a8324b - fine-tuning of white space
- by default consider extra newlines in src for better formatting
- additional flags for control (-newlines, -maxnewlines, -optsemicolons)
- don't print ()'s around single anonymous result types

Status: Comparing the output of pretty with the input for larger files
shows mostly whitespace/formatting differences, which is what is desired.

- Handling of overlong lines
- some esoteric cases which look funny

37bdd3c3f5 - enabled comment printing by default
- changed tab width to 8 chars by default to make test run properly
- excluded 4 files that are not idempotently printed
- fixed a couple of incorrect file position recordings in parser
- fine-tuned layout engine
- white-space formatting reasonable, but not perfect
- no handling of overlong lines

To use with smaller tabs:           pretty -tabwidth=4 file.go
To use with blanks instead of tabs: pretty -usetabs=0 file.go

- use extra src positions to more accurately print comments
- fine-tuned low-level printing routine for comments
- added better debugging support

- comments now appear at the right place (inbetween the right tokens)
- newline control needs improvement (not very hard)
- comment printing disabled for now because pretty is not idempotent
